Have you tired to go into apn settings and making sure they are there and selected
Yes. That was the problem
Thank u!!!
How did you unlock the loader on your cubot Rainbow ?
Have you found a root for it ?
Custom ROMs ?

Hi,
I was in stock IO limited 3.1 and flashed Task 7.1 first and Overcome ROM (latest) to give it a try.
After Overcome I realized that I had no longer access to fastboot option in bootloader, only revocery and odin. I think the problem came here:

Also I lost nvflash posibility, getting rmc 0x4 error all the time (guess it is locked)
Is there anyway to get fastboot back? or to unlock bootloader so I can get trough nvflash?
Now I am trying this threat http://forum.xda-developers.com/showthread.php?t=1119492

AFAIK we cannot unlock a locked bootloader as of now. And why do you need an unlocked bootloader?

What I want is fastboot and not recovery in bootloader, and with a locked bootloader cannot use nvflash in case anything goes wrong.
Tried to change rom first time and got this massage : Fails to 2 boot entering to RSD MODE.
What should I do?
The device was Android 2.3.4 from ORANGE
Is your bootloader unlocked?
As stated above you need to make sure you have an unlocked boot loader in order to flash any ROMS onto the Atrix. Here is a guide on how to accomplish this task:

Rooting does not unlock your bootloader.

You can have an unlocked bootloader and not have "unlocked" on your boot screen.
Please see the following thread:
http://forum.xda-developers.com/showpost.php?p=15573674&postcount=1
The only true way to know if your bootloader is unlocked is to check /sys/firmware/fuse/ReservedOdm.

But still he will have to flash the pudding file to make work the unlocked bootloader which is given in the unlocking thread and will display "UNLOCKED" on the bootscreen.He is on failed to boot screen how can he check ReservedOdm he will find about the bootoader when he will use the fastboot command for unlocking which will display "already unlocked" if his phone bootloader is unlocked.
Hi
I managed to get back to stock rom (restored from a backup), flashed the stock recovery and now i'm unable to relock the bootloader (no more root/superuser)
is there a way to lock it back without htcdev?

run fastboot comand:
fastboot oem lock
it will give your bootloader status to "re-lock"
I got relocked status, I want locked status if possible

Hello Guys, my device got locked after updating my device from miui 8 to miui 9 through a OTA update, i flashed fastboot ROM but it didn't work, I followed a temperory solution not second storage but a solution through ADB drivers ( developers tools ) i formatted through recovery and went to welcome settings from there clicked on terms and conditions and went to Google app searched for settings - created second space then went to activate developers settings and clicked on bebugging on etc , then went back to first storage and activated developers settings and switched OEM unlock , usb debugging on etc than I connected my device to pc, before that I installed abd drivers , from computer I opened CMD and typed few codes like device is connected or not than removed find devices.apk using code by this step I'm able to use my device but I cannot restart or reboot or switch off my device , if I do so it will go to bootloop. By using another code find me device APK will be saved on SD card, a developer said install it as user app ( it can't be installed as user or system app it just installs the app ) and bootloop problem will be solved but when I install it then again device got locked immediately after the install.
So I'm looking for a permanent solution for this, please help me. Thank you
If the device is locked. just unlock it officialy already. and u cannot just remove find device apk without root. u just disabled it.
Need proper answer, waiting for help
I didn't get, What U meant by Device got locked. Few things that can be done, Unlock Bootloader and flash MiUi Fastboot ROM or use any other custom ROMs. Unlock bootloader via Official methods or u can try unofficial methods too.

Is it possible to lock the bootloader on that phone or not ? If yes ,how ?
EDIT : I tried with fastboot commands oem relock but it didn't work .I removed the root but still need to lock the bootlodaer
Hey, you can flash official firmware into your device and get back to the stock firmware without root. But you can't re-lock the bootloader. I have tried so many command in fastboot and any of em doesn't work.

I was able to remove the root manually so no need to reflash stock frimware,but about bootloader still not successed to lock it even via flash tool BLU option. There should be warning that you can't lock it once its unlocked damn..

Yes indeed. I've tried that too. apparently you can't relock the bootloader in newer devices. Only thing to do right now is, hope that Sony will release some kind of commands to relock the bootloader. Unless there's no other way.
